The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00066 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

RÉSUMÉ

Physical plasma as the fourth state of matter comprises highly reactive particles (e.g., reactive species) and different types of radiation. It can be generated under standardized conditions at atmospheric pressure and low temperatures. Plasma is able to generate high-yielding bacterial strains, but this technique has not previously been applied to improve biotechnological processes in medicinal mushrooms. Our study investigated the influences of plasma on the growth and productivity of mycelial cultures of Ganoderma lucidum. Mycelia of G. lucidum were treated as solid pieces or suspended in Hagem medium using 3 different plasma sources: surface dielectric barrier discharge (DBD) plasma source, volume DBD plasma source, and the kINPen09 plasma jet. Treated mycelia were analyzed for biomass production, extract yield, and secondary metabolites. The plasma jet increased total triterpene content. Both DBD plasma sources led to elevated ergosterol content. Increased Β-l-3-D-glucan content was found after exposure to the volume DBD- or kINPen09-treated medium. The changes observed seemed to be dependent on total energy input by the plasma sources and the kind of mycelial treatment (solid piece or suspension; direct treatment or application of plasma-treated medium). In conclusion, physical plasma might be a useful tool for optimizing biotechnological processes in medicinal mushrooms. Further investigations are necessary to clarify whether these changes are stable and heritable, and whether effects can be achieved with other fungal species.
